expression component:
deg(2*pi) -> returns 360
rad(360) -> returns 6.283 (which is 2*pi)
you don't get the same result?
btw, you don't want to connect result of deg() into a component since the data should be in radians not degrees. Convert to degrees when you want the angle to be displayed as text, for example.…

Hi Bojan, I don't think that's the proper way to use the revolve. I would use only half of the profile curve and revolve that 360 degrees (2*pi). Than the projection works fine.
ts of spheres, that are behind the camera, appear. This normally happens with weird lens length settings. The camera needs a 45° viewing angle and therefore might fall into this category. Maybe there is a good solution to get rid of this issue?
Issue #2: I have no clue how to run the screenshot calculation at the end of the solution. Normally I wanted to color the spheres in the video with the "Custom Preview" component, but they would not show up in the saved picture, since custom preview was calculated later than the screenshot component "Cubemap"
Issue #3: The calculation of an equirectangular image takes quite a while. ~4 seconds. Thats still good compared to the 9 seconds i had in the beginning. Multithreading through parallelizing could improve it even more, but it wouldn't work for me.
Especially ISSUE #2 is annoying and does not allow me to create a nice video. I would be glad if someone could assist me in this.
I actually tried already ExpirePreview or Solution, but maybe I used it the wrong way...
Best,
Martin…
seems to be the options I can see.
with hoopsnake, I would like to set each sub axis to rotate 360 degrees while the axis directly one level up in the hierarchy will move 1 degree. repeat this step all the way down to the axis on the base will give me some idea of the physical space that is the robots workspace. but maybe the term workspace more specifically refers to the point the end of the tool can reach so I hope what I have written is not g!misleading.
the galapagos definition you sent me inspired me to look further into this topic. The primary goal is to model the workspace and singularity as if they were an object. I found a PhD work on workspace and singularity here. http://www.europeana.eu/portal/record/2020801/9BB75131B39EE8536A258D9BC9864E89486B0CB0.html?start=6

anyways its saturday so maybe monday i will have somethin! thx again.…
ine will require a points and normal vectors. Give ArrPolar the same parameters used to position the diamonds, but use a point instead of a gem object. This will give you your points. The normals are just a vectors from origin to the points.
4. I added components to the attached file that includes a VB fillet routine. (I don't recall where I found it.) You have to play with the 2 Boolean values depending on the 2 surfaces you feed the routine. Also, be aware that Rhino does not handle filleted surfaces well when they come from Grasshopper. To fix this you have to invoke the Rhino command _DivideALongCreases - otherwise your filleted surfaces will have corners in them.
